Application filed September A12, 19,12. Serial No. 720,042.

To all 'whom t may concern Be it known that I, WILLIAM H. CHIL- DREY, acitizen of the United States, residing at Haw River, in the county ofAlamance and State of .North Carolina, have invented certain new anduseful Improvements in Web-Take-Up Devices for Knitting-Machines, ofwhich the following is a specificatiomi,reference being had to theaccompanyingj'drawing's.

This invention relates tofwelo take up devices for knitting machines andhas for its primary object to provide a device of this character whichwill not be rendered ineffective or unreliable by changes in the gradeor character'cf the thread used' in knitting stockingsand analogousarticles of wearing apparel. l

Anotherobject of the invention is to produce a web take up device foruse upon tubular knitting machines of that character used in theknitting of stockings whereinu the heel of the stocking is provided witha reinforcement, said device at all times maintaining the web in a tautcondition and including a driven friction roller, the operation of whichisautomatically discontinued when the rotary movement of the main shaftis converted into an oscillating movement in the knitting of the heelreinforcement.

A still. further object of the invention resides in the provision of adevice of this character which is extremely simple in construction,reliable and etlicient in its operation and may be applied to knittingmachines of the present'. construction without necessitating anyalteration therein.

Wit-h the above and other objects in view as will become apparent as thedescription proceeds, the invention consists in certain construct-ions,combinations and arrangements of the parts that l shall-hereinafterfully describe and claim.

For a ful-l understanding of the invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1isa side elevation illustrating a portion of a tubular knitting machineand showingthe present invention applied thereto.- FigQQ is an enlargedtop plan view of the take up device; Fig. 3 is an enlarged detailelevation; and Fig. s is a detail perspective view of the huh capthrough the medium of .gwh`ieh the friction roller of the take up devicefis driven.

In the accompanying drawing, I have illustrated only so much of theknitting machineas will enable the application and op'- eration ofthe'invent-ion forming the subjectmatter of the present application, 'tobc readily understood. To this end, l have shown a portion 5 of themachine from which the knitted tubular web W issues.

6 indicates the crown gear which is fixed upon a main shaft driven fromany suitable source of power from which shaft the various elements ofthe machine are actuated.

7 designates a perpendicular rod to the lower end of which a downwardlyextending angularly disposed arml 8 is secured by means of the set screw9.

My improved take up device includes a.

frame 10 which is preferably though not necessarily, of-rectangular formin plan as clearly shown in Fig. 2. This frame is integrally formed uponone end of a ber 11,

said bar being provided at its other end with a sleeve 12 which isloosely engaged upon a transversely disposed rod 13 fixed in the lowerend of the arm 8. A weight 14 is longitudinally adjustable `11p-cn thebar l1 and may be readily secured in, its adjusted position by means ofthe set screw 15,

A roller 1G is provided with stub shafts at its ends which are rotatablymounted in openings provided in the' opposite' longitudinal arms of therectangular frame 10. This roller may be with a ribbed abrio or otherfriction material, though the same is not essential to the operation ofthe device and may he dis- Y pensed with`if desired. Upon one of thestub shafts 17 of the roller 16 a grooved wheel 18 is loosely mountedexterior-ly of the frame 10. The roller shaft projects beyond the wheelhub and is provided with a pin 1.9' transversely disposed therethrough.Y 'A' pin 20 is fixed to the face of the wheel 18 and is adapted forengagement with the pin 19 carried by the roller shaft whereby theroller 16 will he rotated in the movement ofthe wheel 18 in onedirection. The stub shaft at the opposite end of the roller 16 has aratchet 21 fixed thereon for engagement hy a pivotally mounted gravitypawl 2 2. rlhis ratchet and pawl may be dispensed with if desired as itsuse is inno wise essential to the successful operation of the device itwill be noted, from reference to F ig. 3,

rovlded upon its periphery.
